| Last week we tempted you with a preview of the reflex receiver; in this instalment we will continue to develop this idea.
| We already ran into them a few weeks ago: thyristors and triacs – semiconductor switches for DC and AC respectively. As with many other semi...
| Here are some new integrated circuit transducers for AC and DC isolated current measurement up to 300 KHz that offer full isolation, despite...
| To calculate current we normally use a shunt to turn it into a voltage and measure the latter instead. But if we wish to measure the current...
| The most recent PC motherboards provide four pin connectors for cooling fans especially for the CPU fan. The older three pin fans are contro...
| The TDA7052A is a readily available amplifier chip (Farnell # 526198) that has a DC controlled volume input. Here, the IC is used as the var...
| There are very many switching regulator ICs for reducing a dc voltage. In the ‘step-down’ operating mode, an internal switch connects the in...
| The power circuit described in this article is used for obtaining a variable direct voltage source from the 50 Hz a.c. mains supply. The v...
